I've just upgraded my spindle motor to a servo motor, while doing so I needed to increase my kernal speed.I then restarted Mach3, opened motor tuning and nothing, No movement from X,Y,Z or spindle.So i changed it back and still nothing. I closed Mach3 Mill and opened Plasma profile and was able to move X and Y but not Z.I'm really stumped, I'm about to reinstall Mach but first wanted to see if anyone has any idea what could be wrong.
